Loom ATTACHMENT.

Applicationflled August 8, 1925. Serial No. 49,052.

This invention relates to improvements in looms and has particularreference to cloth beam bearings, an object being to provide means forpreventing the beam trunnions from accidentally moving in their bearingsin such manner as to injure the weave of the fabric, yet permit of thecloth beam be ing readily removed and replaced. 5

With the above and other ob 'ects in view, the invention furtherincludes the following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claims.

In the drawings Figure 1 is a fragmentary View illustrating theinvention.

Figure 2 is a fragmentary elevation at right angles to Figure 1.

Figure 3 is a detail perspective View of the retaining block.

Figure t is a fragmentary sectional view looking at the inner face ofone of the bearing brackets, showing a slightly different form ofretaining block;

Referring to the drawings in detail wherein like characters of referencedenote corresponding parts, the reference character 1O indicates aportion of the loom frame to which is attached as indicated at 11 ahearing bracket 12, one of these brackets being positioned at each endof the yarn beam 13 to receive the yarn beam trunnions 14.

The brackets 12 are provided with bearings 16 and 17 the latter beingdesigned to support the beam 13 when the latter is re moved from thebearings 16.

The bearing brackets 12 carry arms 18 and these arms are provided withinclined faces 19 which are adapted to engage in.- clined faces 20provided upon lugs 21, the said lugs extending laterally from retainingblocks 22. As shown in Figure 3 of the drawings these blocks have a lug21 extending from each sideso as to adapt the block for either side ofthe loom frame.

By reference to Figure 1 of the drawings it will be seen that the loweredges of the blocks 22 engage the trunnions 14 and by forcing the blocksinward, the inclined faces 19 and 20 will cause the lower edge of theseblocks to bind tightly upon the trunnions 14 to securely hold thetrunnions in place.

An adjusting bolt 23 extends through the of a bearing notch 16 and theretaining block 22 is so positioned as to prevent accidental outwardmovement of the trunnion. In this form of the invention, the slot 24 isinclined with respect to the bottom edge of the block.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right is herein reserved tomake such changes as properly fall within the scope of the appendedclaims 7 Having described the invention what is claimed is 1. In a yarnbeam bearing for looms, a bearing bracket for supporting the beamtrunnion, an arm extending from said bracket and having an inclined faceextending transversely of the trunnion, a slidingly adjustable retainingblock mounted upon the arm and engaging the beam trunnion, an inclinedlug carried by the block and engaging the inclined face of the arm andmeans to hold the block in adjusted position.

2. In a yarn beam bearing for looms, a bearing bracket for supportingthe beam trunnion, an arm extending from said bracket and having aninclined face extending transversely of the trunnion, an adjustableretaining block, a lug extending laterally from the block and having aninclined face to engage the inclined face of the arm to adjust the blockrelative to the beam trunnion and means to hold the block in adjustedposition. i

3. In a yarn beam bearing for looms, bearing brackets having depressedtrunnion receiving portions for relnova-bly supporting the trunnions ofthe beam, an adjustable block mounted upon each bracket and arranged toprovide a longitudinally disposed outwardly and downwardly inclinedtrunnion engaging face, means carried by the brackets and extendingtransversely of the trunnions to mount the blocks to permit ofhorizontal adjustment and means included in the brackets and blocks tomove the blocks vertically when said blocks are adjusted horizontally. iL;

In testimony whereof I aflix my signature.
